+The generic_x86 board target provides basic services on
+very basic hardware. To build with generic_x86, you will
+need an appropriate kernel for your device (or emulation).
+
+A1. Create a new top level directory and pull the AOSP repository
+        mkdir $HOME/AOSP
+        cd $HOME/AOSP
+        repo init -u git://android.git.kernel.org/platform/manifest.git
+        repo sync
+
+A2. Copy in the buildspeck.mk
+        cd $HOME/AOSP
+        cp build/target/board/generic_x86/buildspec-generic_x86.mk buildspec.mk
+
+A3. Copy in the kernel
+        cd $HOME/AOSP
+        cp ~/bzImage.your_device $HOME/AOSP/prebuilt/android-x86/kernel/kernel
+
+A4. Build
+        cd $HOME/AOSP
+        source build/envsetup.sh
+        lunch generic_x86-eng
+        make -j8
+
+The build will generate some image files whose format may or may not be correct for your
+device.
